我需要在每个密钥之间获取XML文件中的值。例如,我有一个要使用的键列表,每个键都有一个相应的输出元素。密钥可以放在任何地方,没有正确的顺序需要放置密钥。我需要在XSLT 2.0中执行此操作,我不知道如何执行此操作。
键: 元素:
/ OPDH / - ROOT / ELEMENT1 / ABCD
/ EKPH / - ROOT / ELEMENT2 / POIU
/ SGDE / - ROOT / ELEMENT3 / WXYZ
......其他一些钥匙......
注意:键:是BOLD,而Element是ITALIC BOLD。
如果我有这样的示例输入:
1)
<DATA>/OPDH/FLOWING SOLUTION/SGDE/Number0983713/EKPH/Sample test/some other keys/</DATA>
或者可以是:
2)。
<DATA>/some other keys/afdsf/SGDE/Number0983713/some other keys/PIHSAGA/OPDH/FLOWING SOLUTION/some other keys/No exception/EKPH/Sample test/some other keys/</DATA>
预期输出应如下所示:
1
<ROOT>
<ELEMENT1>
<ABCD>FLOWING SOLUTION</ABCD>
</ELEMENT1>
<ELEMENT2>
<POIU>Sample test</POIU>
</ELEMENT2>
<ELEMENT3>
<SGDE>Number0983713</SGDE>
</ELEMENT3>
...some other keys...
</ROOT>
2
<ROOT>
...some other keys...
<ELEMENT3>
<SGDE>Number0983713</SGDE>
</ELEMENT3>
...some other keys...
<ELEMENT1>
<ABCD>FLOWING SOLUTION</ABCD>
</ELEMENT1>
...some other keys...
<ELEMENT2>
<POIU>Sample test</POIU>
</ELEMENT2>
...some other keys...
</ROOT>
谢谢。

以下是使用analyze-string
:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:mf="http://example.com/mf"
exclude-result-prefixes="xs mf" version="2.0">
<xsl:param name="keys">
<element key="/OPDH/">ROOT/ELEMENT1/ABCD</element>
<element key="/EKPH/">ROOT/ELEMENT2/POIU</element>
<element key="/SGDE/">ROOT/ELEMENT3/WXYZ</element>
<element key="/some other keys/">ROOT/FOO/BAR</element>
</xsl:param>
<xsl:output indent="yes"/>
<xsl:variable name="pattern" as="xs:string"
select="concat('(', string-join($keys/element/@key, '|'), ')', '(.*?)', '(', string-join($keys/element/@key, '|'), ')')"/>
<xsl:key name="ref" match="element" use="@key"/>
<xsl:function name="mf:extract" as="element()*">
<xsl:param name="input" as="xs:string"/>
<xsl:analyze-string select="$input" regex="{$pattern}">
<xsl:matching-substring>
<xsl:if test="position() eq 1">
<element path="{key('ref', regex-group(1), $keys)}">
<xsl:value-of select="regex-group(2)"/>
</element>
<xsl:sequence
select="mf:extract(substring($input, string-length(concat(regex-group(1), regex-group(2))) + 1))"
/>
</xsl:if>
</xsl:matching-substring>
</xsl:analyze-string>
</xsl:function>
<xsl:template match="DATA">
<xsl:copy>
<xsl:sequence select="mf:extract(.)"/>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
这会转换输入
<?xml version="1.0" encoding="UTF-8"?>
<Root>
<DATA>/OPDH/FLOWING SOLUTION/SGDE/Number0983713/EKPH/Sample test/some other keys/</DATA>
<DATA>/some other keys/afdsf/SGDE/Number0983713/some other keys/PIHSAGA/OPDH/FLOWING SOLUTION/some other keys/No exception/EKPH/Sample test/some other keys/</DATA>
</Root>
包含提取数据和构建路径的元素列表:
<DATA>
<element path="ROOT/ELEMENT1/ABCD">FLOWING SOLUTION</element>
<element path="ROOT/ELEMENT3/WXYZ">Number0983713</element>
<element path="ROOT/ELEMENT2/POIU">Sample test</element>
</DATA>
<DATA>
<element path="ROOT/FOO/BAR">afdsf</element>
<element path="ROOT/ELEMENT3/WXYZ">Number0983713</element>
<element path="ROOT/FOO/BAR">PIHSAGA</element>
<element path="ROOT/ELEMENT1/ABCD">FLOWING SOLUTION</element>
<element path="ROOT/FOO/BAR">No exception</element>
<element path="ROOT/ELEMENT2/POIU">Sample test</element>
</DATA>
我不太确定这是否做得对,因为我不确定是什么决定了你提供的两个样本的顺序和内容,以及例如/some other keys/
旨在表达。告诉我们结果是否包含您想要的数据,或澄清您的问题以及您展示的样本。一旦我们确定提取了正确的数据,就应该很容易从上述中间结果中生成XML。
答案 1 :(得分:0)
你写的很少关键,所以我认为:
您的输入文件包含两者:
KEYS
标记中),DATA
代码)。这两个标记都是源ROOT
标记的子标记。
KEYS
标记在每一行中包含一对键值和输出路径,其中
应放置此密钥的相应内容。
假设完整输入为:
<?xml version="1.0" encoding="UTF-8"?>
<ROOT>
<KEYS>
/OPDH/ - ROOT/ELEMENT1/ABCD
/EKPH/ - ROOT/ELEMENT2/POIU
/SGDE/ - ROOT/ELEMENT3/SGDE
</KEYS>
<DATA>/OPDH/FLOWING SOLUTION/SGDE/Number0983713/EKPH/Sample test/</DATA>
</ROOT>
然后你可以按如下方式编写XSLT:
<?xml version="1.0" encoding="UTF-8" ?>
<xsl:transform xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0">
<xsl:output method="xml" encoding="UTF-8" indent="yes" />
<xsl:template match="ROOT">
<xsl:copy>
<!-- Divide KEYS into rows -->
<xsl:variable name="keys_1" select="tokenize(KEYS, '
')"/>
<!-- # of rows -->
<xsl:variable name="nn" select="count($keys_1)"/>
<!-- Drop 1st and last (empty) row -->
<xsl:variable name="keys" select="subsequence($keys_1, 2, $nn - 2)"/>
<!-- Divide DATA into tokens -->
<xsl:variable name="data_1" select="tokenize(DATA, '/')"/>
<!-- # of tokens -->
<xsl:variable name="nn" select="count($data_1)"/>
<!-- Drop 1st and last (empty) token -->
<xsl:variable name="data" select="subsequence($data_1, 2, $nn - 2)"/>
<!-- Generate output data for each row from keys -->
<xsl:for-each select="$keys">
<!-- Divide the keys row into tokens -->
<xsl:variable name="parts" select="tokenize(., '/')"/>
<!-- # of tokens -->
<xsl:variable name="nn" select="count($parts)"/>
<!-- Source key - token No 2 (after the 1st '/') -->
<xsl:variable name="srcKey" select="$parts[2]"/>
<!-- path - tokens after 'ROOT' -->
<xsl:variable name="path" select="subsequence($parts, 4)"/>
<!-- Open tags given in path -->
<xsl:for-each select="$path">
<xsl:text>
</xsl:text>
<!-- Spacing -->
<xsl:variable name="nn" select="position()"/>
<xsl:value-of select=
"string-join((for $i in 1 to $nn return ' '), '')"/>
<!-- Print opening tag -->
<xsl:value-of select="concat('<', ., '>')"
disable-output-escaping="yes"/>
</xsl:for-each>
<!-- Find position of the source key in data -->
<xsl:variable name="ind" select="index-of($data, $srcKey)[1]"/>
<!-- Get data from the next token -->
<xsl:value-of select="$data[$ind + 1]"/>
<!-- Close tags given in path -->
<xsl:for-each select="reverse($path)">
<xsl:variable name="nn" select="position()"/>
<!-- Spacing and NewLine - but not for the most inner tag -->
<xsl:if test="$nn > 1">
<xsl:text>
</xsl:text>
<xsl:value-of select=
"string-join((for $i in 1 to last() - $nn + 1 return ' '), '')"/>
</xsl:if>
<!-- Print closing tag -->
<xsl:value-of select="concat('</', ., '>')"
disable-output-escaping="yes"/>
</xsl:for-each>
</xsl:for-each>
<xsl:text>
</xsl:text>
</xsl:copy>
</xsl:template>
<xsl:template match="@*|node()">
<xsl:copy><xsl:apply-templates select="@*|node()"/></xsl:copy>
</xsl:template>
</xsl:transform>
